9. Energy Harvesting (EH) can be defined as the sum of all those processes that
allow to capture the freely available energy in the environment and convert it
in (electric) energy that can be used or stored.

10. Applications for the energy sustainability
EH in buildings – a premise
10
• EH devices are used for powering remote monitoring sensors (e.g. temperature sensors, air
quality sensors), also those placed inside heating, ventilation, and air conditioning (HVAC) ducts.
• These sensors are very important for the minimization of energy consumption in large
buildings

13. Applications for the energy sustainability
Energy Harvesting for monitoring HVACs operating conditions
Currently:
•Power is provided by batteries or EH devices based on thermal or RF methods
•Sensors work intermittently (to consume less power ~ 100µW)
An EH sensor based on piezoelectric material has several advantages being capable to provide up
to 10-15 times more power than currently used devices leading to additional applications or
longer operation time.
